Benefits of technology

[0007]Therefore the object of the present invention is to provide an arrangement for and a method of monitoring and adjusting the control of the electromedical implant for intracardial cardiac therapy with which the mobility of the patient is substantially improved. Along with that the invention seeks to improve in particul

Problems solved by technology

More extensive tasks such as for example monitoring and optimizing the control itself can generally only be implemented to a very limited degree.
That is not only due to the fact that the implementation of such complex control circuits in the limited structural space of the implant encounters at the present time the viable limits thereof.
Rather, such a complex control circuit would also result in a markedly increased level of energy consumption so that the service life of the implant would be curtailed.
Also, in general a defective control logic system cannot check and re-set itself.
A disadvantage here is that the external electrical stimulator is an e

Example

[0047]FIG. 1 shows the structure in principle of an arrangement 10 for monitoring and adjusting a control of an electromedical implant 12 for intracardial cardiac therapy by an external control and evaluation unit 14. The electromedical implant 12 is for example a rate-adaptive cardiac pacemaker.

[0048]The implant 12 and the control and evaluation unit 14 each include a telemetry unit 16, 18 with a respective transmitter 20, 22 and receiver 24, 26, which are suitable for the bidirectional telemetric transmission of data. The data transmitted telemetrically contain for example items of patient information such as the implantation date, the date of the last aftercare, details relating to the symptoms and so forth. In addition diagnostic information, for example relating to atrial or ventricular diagnosis and stimulation can be communicated. In addition battery and electrode parameters, in particular the currently prevailing values of battery voltage, internal battery resistance and cur...

Abstract

An arrangement (10) for monitoring and adjusting a control of an electromedical implant (12) by means of an external control and evaluation unit (14) is made up of the electromedical implant, the external control and evaluation unit and a central, autarchically runnable evaluation logic means (30) which controls the activities of a telemetry unit (16) and a memory unit (34), which is connected to a clock and timer unit (42) and which on the basis of certain communicated data ascertains control sequences and control parameters for monitoring and adjusting the implant and co-ordinates the transmission thereof to the implant. An expert system (ES) may be adapted to assess all monitoring and adjusting tasks on a patient-individual basis.

Description

[0001]The invention concerns an arrangement for monitoring and adjusting a control of an electromedical implant for intracardial cardiac therapy by means of an external control and evaluation unit, an associated method and the external control and evaluation unit itself having the features set forth herein.BACKGROUND OF THE ART[0002]Electromedical implants such as cardiac pacemakers and defibrillators have proven to be an extraordinarily successful instrument for the electrotherapy of bradycardiac and tachycardiac rhythm disturbances. In that respect the task of implants of that kind is not restricted just to merely delivering electrical pulses to the atrium or ventricle myocardium in order there to trigger off depolarization. Rather, modern pacemakers and defibrillators involve sensors and evaluation circuits which permit controlled or regulated frequency adaptation, adaptation of pulse amplitude, pulse width and AV-time for therapy optimization purposes. In that way the aim is for...
